Auto Upload definitely sounds very scary the first time you're prompted about it. Most people fear that every photo they take will automatically be publicly shared on Google+ (which isn't the case; it's uploaded to Google+ Photos as a private document that "only you" can see) and go out of their way to make sure it's off.
I've found the feature convenient and look at most of my pictures that way. It's a bummer when I have to connect my phone via USB cable and pull stuff off that way now (especially since Android is now MTP access only, but let's not go down that road...).
